Specification of Letters Patent.

Patented Mar. 11,1913.

Application filed March 29, 1912.y Serial No. 687,189.

To all whom it may concern.' v

Be it known that I, CARL J. SnvnnsoN, of Minnea olis, Hennepin county,Minnesota, have invented certain new and useful' Im rovements inStorm-Sash Fasteners, of which the following is a specification.

The object of my invention is to vprovide means by which, Vwhen thewindow sash is opened or closed, the storm sash will he correspondinglymoved. i

A further ob'ect is to provide a fastening device designed to bepermanently mounted on the storm sash and having means for easil andquickly connecting' it with the win ow sash.

A further object is to provide a fastening device which, when the windowsash is closed, will draw the storm sash snugly to its seat, therebypreventing it from shaking or rattling in the wind.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claim.

In the accompanying drawings forming part of this specification, Figure1 is a vertical, sectional view through a wind'ow frame sash with myinvention applied thereto, showing the storm sash in its closedposition, Fig. 2 is a similar view, showing the storm sash in its openposition, Fig. 3 is a detail side view of the sash fastener, Fig. 4 is alan view of the same.

In t e drawing, 2 represents the window sill, 3 the window frame and 4the lower sash of the window, all ofordinary construction.

6 is the storm sash, hinged at 7 by any suitable means to the windowframe and having the usual beveled edge 8 at its lower end to fit snuglyagainstthe inclined surface of the window sill.

Many devices have been employed for operating the storm sash to onen orclose it when the window sash is raised, but all of them have been moreor less objectionable,V- principally on account of their insecurefastening and the fact that they allow the storm sash to shake andrattle in the wind, and even when closed do not hold it securely.Furthermore-in many devices it and then operate some mechanism foropenmg or closing the storm sash. The connection which l prefer toemploy between the window sash and the storm sash consists of a metalbar9 having a lug 10 at one end to engage an ear 11 that is fastened to thelower rail of the window sash. rl`he bar 9 is preferably of fiat metaland its inner portionis edgewise to the window sash, while its outerportion l2 is twisted into a plane at right angles substantially to theplane of the inner portion and is curved slightly, as indicated in Fig.3 and provided with an eye 13 at its outer end which engages a secondear 14 mounted on the storm sasi.

In placing this device on the window, the parts are adjusted so that thestorm sash y will contact with its seat before the window sash is entirely closed, and consequently the final closing movement of the windowsash will flex the part 12 of the bar 9 and draw the storm sash to itsseat with a yielding tensionythereby excluding the cold air andpositivelyl preventing the storm sash from rattling in the Wind. Thehooked end is made to fit snugly onthe bar of the ear 11 and the eye atthc opposite end of the fas/- tener also fits snugly on the bar of theear 14 and consequently, even when the storm sash is open, it will beheld securely against shaking or rattling.

The fastener will be permanently mounted on the storm sash, one on eachside thereof, and when the sash is hung on the window the inner hookedends will be engaged with the ears on the window sash so that wheneverthewindow sash is raised or lowered a corresponding movement of thestorm sash will take place. A

I do not wish to he confined to the precise manner of mounting thefastening device illustrated herein or to the shapev of the fasteningbar, as in various ways the details may be modified and still be withinthe scope of my invention. p'

I claim as my invention:-

The combination, with a Window frame and a. window sash and a storm sashhinged on said frame, of a bar pivotally connected with a side rail ofsaid storm sash and with the lower rail of said window sash, said barhavingr a curved, flexible portion, Jche distance between the pivots ofsaid bar on said sushes increasing with the closing of the window sash,whereby said curved flexible portion will be put: under tension when thewindow sash is closed to hold the storm sash snugly on its seat.
